How to serialize query object with custom delimeter

[Mazas17]

I have yaml file:

openapi: 3.0.1
info:
  title: My API
  version: v1
paths:
  # /users;id=3;id=4?metadata=true
  /users:
    get:
      parameters:
        - in: query
          name: offset
          schema:
            type: integer
          description: The number of items to skip before starting to collect the result set
        - in: query
          name: limit
          schema:
            type: integer
          description: The numbers of items to return
        - in: query
          name: origin
          style: form
          explode: false
          schema:
            type: object
            properties:
              city:
                type: string
              zip:
                type: string
      responses:
        '200':
          description: A list of users

When I click "execute", the generated Curl looks like this:
curl -X GET "https://editor.swagger.io/users?offset=2&limit=12&origin=city,atlanta,zip,303" -H "accept: */*"
However, I need it to be like this:
curl -X GET "https://editor.swagger.io/users?offset=2&limit=12&origin=city:atlanta|zip:303" -H "accept: */*"

Is it possible to do this? I could not find any info in documentation about setting custom delimeters.

As you demonstrate, the style field is a property of the parameter object, and it is this which along with explode which controls the parameter serialisation.

So you could achieve various combinations of separators as listed here but there is no way to attach custom delimiters to the keys and values or to each individual property (this would be ambiguous with regard to optional object properties).
